    Turntable ground question

    Post by bubbasweet on Mon Aug 01, 2016 1:26 pm

    On an amp with 2 PAM-1s and 2 Mk3s. Where should I put the ground wire for my Dual turntable. I used the negative lug on the speaker ground on one if the mark3s and it seems to be dead quiet. Is there a proper target? All units are plugged into same power bar so I do not get a ground loop.. Are turntable supposed to be grounded to the preamps or to the power amps or doesn't matter..?

    Ideally I would say one or the other of the PAM-1s, but if it is quiet where you put it, you could let sleeping amplifiers (and ground wires) lie.

    "Let sleeping amplifiers lie" was a favorite quip by the late Bob Tucker of Dynaco...the original, REAL Dynaco, not the Panor pretender...he was still there when Dynaco was an independently-run subsidiary of Tyco.

    Yep, what GP49 said. Whatever works. If you start adding SUTs and separate phono pre-amps into the mix then it's a whole new ballgame but a solution will always present itself. It's a matter of patience and how much hair you want to tear out. I would build two ground wires with spades or whatever, just to cut experimentation time in half.
